FLUSHING DEVICE FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 486,994, dated November 29, 1892. Application filed May 19, 1892. Serial No. 433,507. (No model.)

To all whom, it may Gull/06772:

Be it known that- I, HENRY O. l/VEBER, a citizen of the United States, residing at- Ohicago, in the county ofOook and State of Illinois, have invented a new and useful Flushing Device for Water-Closets, of which the following is a specification.

My invention relates to the means used to control the flow of water for flushing Waterclosets; and my objects are to so change the construction of the ordinary siphon flushingvalve that its use'will be attended with more satisfactory results than heretofore by the entire absence of noise above that of the rush of the flushing-water into the water-closet when the siphon is broken by the inrush of air near the surface of the water in the supply-tank. Another object is the application to this flushing device of an afterflow-valve, which combination adapts the operative mechanism to several kinds of water-closets without material alteration, which objects are attained by the mechanism and construction shown in the accompanying drawings, in which Figure 1 is an elevation of my new siphon flushing-valve, the sides and bottom of the tank being broken away to show the relative position of the valve, this view also showing a portion of pipe and valve-chamber of the afterflow-valve broken away to show construction of valve, its position, and the course of the afterflow-water to where it is discharged. Fig. 2 is a side elevation of the flushing-siphon detached from the tank, Fig. 1. Fig. 3 is a longitudinal sectional view of the flushing-siphon on line A B, Fig. 5. Fig. 4 shows tank broken away similar to Fig. 1; also shows vertical section of flushing-siphon at a right angle to the section shown in Fig. 3. The arrows shown in Fig. 4 indicate the course of the current of water from the tank at the instant of starting the siphon. Fig. 5 is a transverse section of the flushing-siphon on line D, Fig.2. Fig. 6 is a transverse section of the flushing-siphon on line 0 D, Fig. 2. Fig. 7 is a view of the admission-valve for supplying water to the tank, enlarged from Fig. 1, the valvecasing being broken away, showing, also, afterfiow-valve in partial section. Both supply-valve and afterflow-valve are closed. Fig. 7 8 shows section similar to Fig. 7, but with supply-valve and afterflow-valve both open.

Similar numerals indicatecorresponding parts throughout the several views.

1 is an ordinary tank, and at 2 is a valveseat whose casting is prolonged downward through the bottom of tank 1.' This seat 2 has a flange 3 at the top, which contacts with the inside of the tank at the bottom thereof, being held in water-tight position by means of a nut 41: atthe bottom of the tank, as shown.

' At is the nut which couples vertical pipe 6, which pipe carries the flushing-water from the tank to any form of watercloset below, as usual.

The flushing device proper consists of a cylindrical portion 7, which is closed at the top end and is' reduced in diameter for a short distance at thelower end, which forms the cylindrical portion 8,a shoulder 9 being formed at the junction of cylindrical portions 7 and 8, which shoulder is formed to fit the valveseat 2, so that when this shoulder is in contact with seat 2 no water can pass into pipe 6 from tank 1. The cylindrical portion 7 of the flushing device is divided longitudinally into three chambers 10, 11, and 12 by partitions 13 and 14, which partitions do not extend to the top inside of the cylinder, but leave a passageway 15, Figs. 3 and 4, by which water may flow from chambers and 11 over into chamber 12. It will be noticed that the walls of the partitions of chamber 11 extend above the portion of partition 13, which separates chamhere 10 and 12. The partitions extend downward and are secured at the bottom of cylinder 7, where it joins cylinder 8, so that there is no communication between the chambers at the bottom. Chambers 10 and ll-each have a mouth, respectively 15 and 16, where they terminate, these mouths admitting water to the chambers from tank 1, as will be fully shown. Chamber 12 occupies nearly one-half of the area of cylindrical portion 7 and extends the whole length thereof, and thence extends down into the full inside diameter of short cylinder 8, which cylinder is provided with several side openings 17 for the purpose, as will be shown. The bottom of short cylindri- ICO cal portion 8 consists of a diaphragm or head 18, through which are a number of perforations 19, Figs. 3 and 6, which perforations are for the purpose of increasing or decreasing a esaeee the flow of flushing-water, as may be desired, by plugging one or more of the holes, one of the holes 19 in Fig. 6 being plugged for illustration.

The chamber 12 is provided with a series of horizontal baffles 20, which are attached at the sides of the chamber alternately on opposite sides, as is shown in Fig. 4, top view Fig. 5. These baffles 20 extend part of the Way across the chamber, leaving a passage-way for the water in a zigzag direction, as shown by the arrows, Fig. 4, and thus prevent the water from attaining an undesirable rate of velocity at the time the siphon is broken, as will be explained in describing the operation of the device.

The usual float for closing the tank-supply valve 21 is shown at 22, which is attached to a lever 23 and pivoted at 24 to a lug of the valve-chamber 25, as usual and well understood by those skillcd in the art to which thisinvention pertains.

At 26 is a passage-way which leads down under the valve seat 2, which passage-way extends through a pipe 27 and enters the valvecasing28, and thenceinto valve-casingorchaim ber25. Valve-casing 28 is provided with asmall piston-valve 29, through which is a passage 30, the lower part of the valve 29 being solid and capable of closing the passageway 26 when valve 29 is in the position shown in'Fig. 7. When valve 29 is in the position shown in Fig. 8, water can pass from valve-chamber 25 through pipe 27 and valve-passage 30 to the space under valve-seat 2 whether the flushing-cylinder 7 is on its seat in the closed position shown in Fig. 1 or not. The office of valve 29 is to provide an afterflow, the valve to be operated by the action of float 22, the valve being connected by a link 29' to the shank of lever 23, as plainly shown in Figs. 1, 7, and 8, valve 29 being fully open when tank 1 is exhausted and the siphon broken in cylinder 7, valve 29 remaining open until the water has risen in tank 1 to almost one-half its normal height, when by the upward motion of float 22 valve 29 is closed. In'the meantime a small quantity of water has passed through the small opening 30 and, running through pipe 27 and thence down pipe 6 to the water-closet, has gradually filled the depressed portion of the siphon and sealed it against the passage of gas, as usual, and with no possibility of admitting sufficient water to pipe 6 as to cause a start of water through the siphon in cylinder 7 in the supply watertank 1.

It will be noticed that the upper margin of mouth 16 of chamber 11 is higher than the upper margin of mouth 15 of chamber 10, so that air will be taken first into mouth 16, causing an instant break of the siphon in cylinder 7 before the declining water in tank 1 falls to the level of mouth 15, the baffles 20 in cylinder 7, Fig. 4, preventing the descending water from attaining a very highwelocity, with the consequent low velocity of the current of air entering mouth 16, and the absence of noise therefrom, the partitions inclosing longitudinal siphon-chamber 11 extending, as before stated, nearly to the top of the inside of cylinder 7, so that air admitted at month 16 passes at once to the extreme top of the cylinder and effectually prevents the gurgling sounds incident to the ordinary construction of flushing-'siphons.

In operation the cord 32 is pulled downwardly, which action through the medium.of lever 31, which is attached to the top of cylinder 7, lifts the cylinder to the position shown in Fig. 4, when water from tank 1 rushes into the lower cylindrical portion 8 of the flushing device through side ports 17, thence down through holes 19 of diaphragm 18, thence down into pipe 6 and to the water-closet, which inrush and descent of water serves as a piston to remove the water f romthe chamber 12, and a partial vacuum is produced in the top portion of cylinder7 when the water in longitudinal chambers 10 and 11 rushes up and over the top of partitions 13 and 14, forming a siphon action, which is supplied with water from the two mouths 15 and 16, which are open to the water in the tank. If now after water (from the tank) siphons over the partition 13 from both chambers 10 and 11 into chamber 12, the cord 32 is released, the cylinder 7 will drop of its own gravity and, contacting with seat 2, stop the passage of water at this point; but the siphon action being established, the water will continue to flow from tank 1 up chambers 10 and 11, thence down chamber 12 overbaffles 20 to pipe 6, and thence down to the water-closet until the level of the water in the tank has fallen to the upper margin of mouth 16, when air is admitted to the top portion of cylinder 7 and the siphon action instantly broken. When the tank is empty, float 22 is at the bottom of the tank, its lever 23 in the horizontal position shown in Fig. 8, where supply-valve 21 is-lifted from its seat and water is flowing from the watersupply out into the tank to again fill it, valve 21 having the closed position shown in Fig. 7 when float 22 is at the top of the tank, as

, shown in Fig. 1.

It is well known that wherewater-closets are provided with a siphon-seal below or at one side of the bowl' when they are flushed with a sufficient quantity of water to serve the purposes the action is so vigorous that the water which should remain in the pocket portion of the siphon is all blown over into the long leg of the siphon by the inrush of air, so that the closet is without the water seal so necessary to prevent the passage of sewer-gas. The small valve 29, which has been partially described, is always open just after the siphon action in cylinder 7 is broken, and this valve continues to be open for some time afterward, until by the upward motion of float 22 lever 23, through the attached link 29, lifts the valve to the closed position, Fig. 7, the small stream of water from valve 29 gradually filling the seal portion of the bowlsiphon as desired.

I claim as my invention cure by Letters Patent 1. A flushing device for water-closets, consisting of a three-chambered siphon,two chambers of which are for receiving water from the tank, said two chambers forming the short leg of said siphon and one chamber, into which water is delivered from said short leg, forming the long leg of said siphon, the chamber comprising said long leg provided with horizontally-disposed baffles arranged in the manner and for the purpose substantially as described.

2. A flushing device for water-closets, consisting of a three-chambered siphon, two chambers of which are for receiving water from the tank, said chambers forming the short leg of said siphon and one chamber, into which water is delivered from said short leg, forming the long leg of said siphon, the chamber serving for said long leg having horizontallyand desire to sedisposed baffles, as described, said long log terminating at the lower end thereof in a cylindrically-shaped chamber whose bottom is provided with 1nultidischarge-openings,which serve, in combination with said bafiles, for the purpose substantially as described.

3. A flushing device for water-closets, com prising a threechambered siphon, as described, said siphon within a casing, which also forms a valve for admitting water to the discharge-pipe to start said siphon, a supply- I valve for filling the tank, said valve operated by the rise and fall of the water in the tank, a pipe forming a communication between the chamber of said supply-valve and the discharge-pipe under said siphon-casing, said pipe from said supply-valve casing having a valve to open and close communication with said supply-valve casing, said valve in said pipe operated by the means which operates the tank-supply valve at the time and for the purpose substantially as described.

In testimony'that I claim the foregoing I have hereunto set my hand, this 3d day of May, 1892, in the presence of witnesses.
